Matthew 15:18

18 But the things which proceed out of the mouth, come forth from the heart, and those things defile a man.

Matthew 15:18 Meaning and Commentary

Matthew 15:18

But those things which proceed out of the mouth
Meaning not material things, as spittle, vomit but, as it follows, which

come forth from the heart:
are first conceived and formed there, and then come forth from thence, and are expressed by the mouth; as all idle words, foolish talking, filthy jesting, unsavoury communication, and every word that is rotten and corrupt, or which is done in the life and conversation;

and they defile the man:
the heart is the corrupt fountain from whence all moral defilement flows; and sinful words and actions are the impure streams, which spring from thence, and increase the moral pollution of human nature.

Matthew 15:18 In-Context

16 But he said: Are you also yet without understanding?

17 Do you not understand, that whatsoever entereth into the mouth, goeth into the belly, and is cast out into the privy?

18 But the things which proceed out of the mouth, come forth from the heart, and those things defile a man.

19 For from the heart come forth evil thoughts, murders, adulteries, fornications, thefts, false testimonies, blasphemies.

20 These are the things that defile a man. But to eat with unwashed hands doth not defile a man.
